WERKSTATT DER PFÄHLER

The Werkstatt der Pfähler(Werkstatt the Impaler) is a Moog Werkstatt-Ø1 that has been cut up and extensively modified. There is a huge beast inside these little synths that can only be accessed through modifying.﻿ There are 2 versions available: Standard and Full. The Standard version is perfect for incorporating into an existing Eurorack modular system. Most of the header patch points have been brought to the rear of the unit to 3.5mm Jacks. Most importantly, the EG can be triggered by an external gate. This is not possible without modification. The Full version takes the standard and brings it to a stand-alone powerhouse! In addition to the CV In’s and Out’s at the rear, buffers are added to all CV Out’s (these are circuits that keep critical voltages, like the raw VCO waveforms from sagging when used to drive external gear). The CV Out’s are wired to TRS jacks, giving a total of 8 individual outputs. A MIDI 2 CV (MINICV) converter is added to drive the VCO and EG. Additionally, the CV & Gate generated by the MIDI 2 CV is brought to 2 jacks, so when the Werkstatt is not in use, it can be used to drive other analog gear that does not have MIDI, but does have CV & Gate In’s. A mixer is added to give volume control over the Werkstatt VCO and External Audio. Additionally, the VCF is wired to the Audio In jack, so when nothing is plugged into the jack, the Audio In volume knob will send the VCF back into itself for some intense filter overdrive! A 2nd glide circuit is added in line with the VCO CV In. The Werkstatt Glide potentiometer is removed and replaced with a dual gang potentiometer. This way one knob can control both the Werkstatt glide and the external pitch glide. The VCO Wave selector switch is removed and a mixer circuit is added so the 2 waveforms can be continuously blended from one to the other. Lastly, there is a Fine Tune knob added. Both mods come with high quality Lexan Overlays by SynthGraphics (similar to the ones used on production Moogs), and all mods are backed by a 1 year warranty.*

SPECIFICATIONS

< STANDARD MOD >

7 CV Inputs:

Gate

VCO EXP (Pitch)

PWM (Pulse Width Modulation). This mod is wired so that when a jack is inserted, the PWM DEST switch is deactivated and is rerouted to the jack instead. When nothing is inserted it behaves normally.

LFO. Any positive or negative voltage will change the LFO frequency.

VCA. Drive the VCA with an external envelope generator, LFO, etc.

Cutoff Frequency

Audio In. When a jack is inserted, it disconnects the Werkstatt VCO to the Filter. Any audio sent from the jack will pass through the filter instead. The VCO passes through as normal when no jack is inserted.

5 CV Outputs:

VCF. The raw audio from the VCF before the VCA

LFO Triangle

LFO Square

VCO Saw

VCO Square

8 CV Outputs (T=Tip R=Ring):

Gate (T)

Trig (R)

KB (T). The Werkstatt Keyboard outputs 3V/Oct. It requires calibration for standard 1V/Oct. A trimmer is added in line and set to standard 1V/Oct.

All CV Outputs are buffered.

﻿Note: below "MIDI IN" is where the 3.5mm TRS Jack will be fitted. The original design used a standard sized MIDI DIN connector, which it was found didn't fit as well as we originally though﻿t.

All units will be fitted with a MINICV MIDI 2 CV PCB.

MIDI IN 3.5mm TRS Jack (A 3.5mm TRS to Male MIDI Connector will be supplied with each unit)

MIDI CV Out

MIDI Gate Out

Main Out (Volume Control of the ¼” Main Output)

Audio IN (Volume control of the Audio IN Jack. When nothing is plugged into the jack, the Audio Volume will send the VCF back into itself for classic filter overdrive)

2nd Glide allows any external CV that is plugged into the VCO EXP jack to past through a glide. The Werkstatt Glide Pot is removed and replaced with a dual gang pot, allowing 1 knob to control both the Werkstatt and external pitch in glides.

Variable Waveshape. The VCO Pulse & Saw switch is removed and replaced with a pot that allows the 2 waves to be continuously blended with each other, creating waveshapes previously unavailable.

Fine Tune. A pot will be mounted to the side of the Werkstatt by the VCO allowing the VCO Frequency to be finely adjusted, making it easier to tune the VCO.

4 3.5mm TRS Male to Y Female 3.5mm TS Cables

1 6ft 3.5mm TRS Male to Standard 5 Pin Male MIDI Connector Cable
